DELIYERING MOVING Application filed March 6, '1926. Serial No. 92,904.

This invention relates to the handling of moving webs of material such, for example, as the product of a rubber sheeting or coating calender. It. is frequently desired to wind up in rolls of definite amount the stock continuously being delivered from a calender. Formerly this has been done by ca'rrying the calendered stock upon a conveyor, above which are a pair of spaced wind-up devices, severing the stock after one of the wind-up devices is full, and starting the leading end of the severed web by hand into the second wind-up device. It is the object of the invention to provide awmethod and a mechanism for picking up the leading end of the stock W1th011i3 the necessity of the operators touching it with their hands, and to reduce the number of men necessary to operate the wind-up;

Referring to the drawings,

Fig. 1 is a side elevation of a wind-up device embodying my invention;

gig. 2 is-a partial top plan of the device; an

Fi 3 is an enlarged sectional detail of a pic -up device.

The calendered web on is shown as coming to the wind-u over an equalizing roll 10 and cooling ro ls 11. From the cooling rolls the web is received upon a belt conveyor 12, driven in any suitable manner at a speed coordinated with that of the calender. One suitable driving arrangement is shown in my application Serial No. 20,398, filed April 3, 1925, jointly with P. L. Butterfield. At 13 is located a cutting device for severing the web entirely across when one, wind-up device is full and it is desired to start winding 9. fresh roll. The cutting device is illustrated as of the t described fully in my joint application with P- L. Butterfield filed November 13, 1925, Serial No. 68,839.

Located on spaced standards 14 are spindles 15, driven by chains 16 from a'motor 17, the spindles frictionally engaging wind-up rolls 18. This friction drive forms of itself no part of my present invention and is de- I scribed in detail in application Serial No. 20,398 above referred to. Also mounted on the standards 14 are spindles 19 which are adapted to carry r lls of a liner material 8. On short standards 20 is journaled a frame composed of side pieces 21 pivoted to a crossof picking the web m off the shaft 22. joined at one side by a shoe 23 and at the other by a roll 24. A handle 25 on the cross-shaft permits manual rotation of the frame to bring either the shoe or the roll into a position facing the advancing stock.

When the Wind-up device is engaged in spooling up stock the liner 8 passes from spindle 19 around roll 24 and over the curved surface 26 of the shoe to the wind-up roll 18. (See the unit at the left in Fig. 1.) The eh m passes under a roll 27 and joins the liner either at the roll 24: or the shoe 23. Both webs are wound together upon the wind-up roll, the liner acting to prevent adhesion of adjacent turns of the sticky rubberized stock. In case the web at is not of an adhesive nature, or is not to be wound up, the liner .9 may be replaced by a short hner suflicient in length to get the stock started upon the wind-up roll.

When a out has been made the trailing end of the severed web is drawn into the wind-up roll completing the winding of that roll while the leading end, indicated at 28 in Figs. 1, 2 and 3, drops upon the conve or and is carried along by it. Before it as reached the wind-up upon which it is to be spooled, the operator turns the handle of the pick-up frame associated with that wind-up so as to bring the shoe 23, with the liner 8 passing around it, into contact with the belt 12 as shown at the right in Fig. 1 and also in Fig. 3. The travel of the liners being, at the point of contact with the belt, in a direction opposite to the motion of the leading end 28, operates to pick this from the surface of the belt. The direction ofmotion of the liner is immediately changed, however, by its passage around the end of the shoe (see the-arrows in Fig. 3) and carries the web 111. along with it. After the leadmg end 28 has been fully started the handle 25 s turned to the position shown at the left 1n Fig, 1, in order to reduce the friction of the liner on the conveyor and around the edge of the shoe.

These operations may be repeated, alternating at the full speed of the calender, as often as it is desired to change spools. It w1ll be found that in addition incident tothe elimination of the necessit belt by han to the saving in labor abrupt turn in a direction of motion op claim 1. A method of picking up stock being delivered on a conveyor belt, which comprises causing a conveying web to pass through an posite to that of the belt, and substantially 1n contact with the belt ahead of the leading end of the stock, whereby the stock will be lifted from the belt and carried upon the web.

2. A pick-up device for stock being delivered on a conveyor belt, which com rises a conveying web, a guide directin t e web through an abrupt turn substantiaflly in contact with the belt, and means for causing the web to travel past the guide in a direction opposite to the path of travel of the belt.

3. A pick-up device for stock being delivered on a conveyor belt, which comprises a ivoted frame, a guide member held by the rame and extending across the path of the stock, a guide roll journaled in the frame and located therein at the opposite side of the pivot, and a conveyin web looped around the member and the ro whereby the frame may be rotated to bring the member or the roll adjacent the belt.

4. A pick-up device for stock being delivered on a conveyor belt, which comprises a pivoted frame, a guide shoe mounted therein and convexed towards the conveyor belt when the frame is rotated so as to bring the shoe closely adjacent the belt, a guide roll journaled in the frame on the opposite side of the pivot from the shoe; and a conveyin r, web passing around the shoe and the roll, a1 constructed and arranged so that when th shoe is adjacent the belt the web will make an abrupt turn therearound so as to pick up the stock from the belt, and so that when the frame is swung around the roll will travel into position to guide the web and thus relieve the friction of the latter upon the shoe.
